摘要： A current collector capable of relaxing stress and of improving charcteristics, an anode using the current collector, and a battery using the current collector are provided. An active material layer containing Si is provided on a current collector. The current collector contains Cu. Where a peak area resulting from (220) crystal face of Cu obtained by X-ray diffraction is I220, and a peak area resulting from (200) crystal face of Cu obtained by X-ray diffraction is I200, ratio I220/I200 as a ratio of the peak area I200 to the peak area I200 is 2.5 or less. Thereby, even when the active material layer is expanded and shrunk due to charge and discharge, the stress can be relaxed, and separation or the like of the active material layer can be prevented.

摘要： A negative electrode of a nonaqueous secondary battery is formed of a carbonaceous material. The ratio RG=Gs/Gb of the degree of graphitization Gs of the carbonaceous material, determined by a surface-enhanced Raman spectrum, to the degree of graphitization Gb, determined by a Raman spectrum measured using argon laser light, is at least 4.5. Alternatively, the carbonaceous material has a peak in a wavelength range above 1,360 cm−1 in a surface-enhanced Raman spectrum which is measured by-the same surface-enhanced Raman spectrum. The deterioration of the nonaqueous secondary battery is suppressed during use in high-temperature environments and high capacity is maintained for long periods.
